A fixed plate moves a ring downwards, pushing a clamping block to move and clamping a laser pointer. A multi-stage electric push rod is installed inside the connecting box. The position of the rectangular box is adjusted using the multi-stage electric push rod, the fixed block, and the slider.

[0003] However, in order to improve engraving efficiency, most existing engraving machines are equipped with multiple engraving drill bits on a single engraving machine. Using this device to clamp and install the engraving drill bits requires the same number of clamping devices, resulting in a large number of required parts. The clamping devices use more motors, which not only increases the difficulty of control but also wastes equipment resources and has poor practicality. Utility Model Content

[0004] To address the problem of excessive motor usage and wasted equipment resources in existing technologies, this invention provides a carving machine clamping device. This device utilizes a connecting shaft combined with a transmission mechanism to achieve the effect of adjusting multiple clamping devices using a single motor. The specific technical solution is as follows: A carving machine clamping device includes: a carving machine body; an electric slide rail and a processing table are mounted on the top of the carving machine body; the electric slide rail and the processing table slide relative to each other; the electric slide rail is located above the processing table; multiple connecting boxes are slidably connected to the front end of the electric slide rail; a clamping plate is slidably connected to the front end of each connecting box; a groove is formed at the front end of the clamping plate; a double-threaded rod is rotatably connected within the groove; both ends of the double-threaded rod penetrate the clamping plate; couplings are installed at the opposite ends of two adjacent double-threaded rods; and a connecting shaft is installed between the two couplings.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-5 A carving machine clamping device includes: a carving machine body 1, an electric slide rail 3 and a processing table 10 mounted on the top of the carving machine body 1, the electric slide rail 3 being used to move a carving drill bit or laser pointer, and the processing table 10 being used to place the carving workpiece; the electric slide rail 3 and the processing table 10 slide relative to each other, and the electric slide rail 3 is located above the processing table 10.

[0023] At least two connecting boxes 4 are slidably connected to the front end of the electric slide rail 3. A clamping plate 5 is slidably connected to the front end of the connecting box 4. A hydraulic cylinder is installed inside the connecting box 4. The connecting box 4 drives the clamping plate 5 to rise and fall through the hydraulic cylinder. A slide groove 6 is opened at the front end of the clamping plate 5. A double threaded rod 7 is rotatably connected in the slide groove 6. Both ends of the double threaded rod 7 pass through the clamping plate 5. A coupling 11 is installed at the opposite ends of two adjacent double threaded rods 7. A connecting shaft 12 is installed between the two couplings 11. When one double threaded rod 7 rotates, the other double threaded rods 7 will rotate through the connecting shaft 12.

[0024] As a preferred embodiment, the front end of the clamping plate 5 is provided with a second groove 61, which is located above the first groove 6. A double threaded rod 71 is rotatably connected inside the second groove 61. Both ends of the double threaded rod 71 penetrate the clamping plate 5. The first double threaded rod 7 and the second double threaded rod 71 are arranged in parallel. Both the first double threaded rod 7 and the second double threaded rod 71 have threads in opposite directions on both sides with the middle as the center.

[0025] As a preferred embodiment, both double-threaded rod 7 and double-threaded rod 2 are further provided with two symmetrically threaded sliders 8 on their outer walls. Each slider 8 has a clamping block 9 installed at its front end. The rotation of double-threaded rod 7 and double-threaded rod 2 causes the sliders 8 on both sides of the surface to move in opposite directions, achieving the effect of clamping and releasing. A transmission mechanism 15 is installed between the outer walls of one side of double-threaded rod 7 and double-threaded rod 2, and double-threaded rod 7 drives double-threaded rod 2 to rotate through the transmission mechanism 15.

[0026] As a preferred embodiment, the transmission mechanism 15 further includes: a first pulley 151, a second pulley 152, and a connecting belt 153. The first pulley 151 is fitted on one side of the outer wall of the double threaded rod 71, the second pulley 152 is fitted on one side of the outer wall of the double threaded rod 71, and the connecting belt 153 is installed between the first pulley 151 and the second pulley 152.

[0027] As a preferred option, a support plate 13 is installed on one outer wall of one side of the clamping plate 5, and a motor 14 is installed on the top of the support plate 13. The output end of the motor 14 is connected to the opposite double threaded rod 7. By driving all the double threaded rods 7 and double threaded rod 71 to rotate through a single motor 14, the equipment resources are saved.

[0028] As a preferred embodiment, the concave surface of the clamping block 9 is provided with a slot 16, and an inner slide plate 18 is slidably connected to the inner wall of the slot 16. A spring 17 is installed between the slot 16 and the inner slide plate 18. A connecting block 19 is installed at the end of the inner slide plate 18 away from the spring 17. A rubber plate 20 is installed at the end of the connecting block 19 away from the inner slide plate 18. At least two protrusions 23 are installed at the end of the rubber plate 20 near the clamping block 9. A limiting groove 22 is provided on the side wall of the slot 16. A limiting block 21 is slidably connected in the limiting groove 22. The limiting block 21 is connected to the inner slide plate 18. The limiting block 21 and the limiting groove 22 prevent the inner slide plate 18 from extending out of the slot 16.

[0029] As a preferred embodiment, the two sides of the engraving machine body 1 are slidably connected with support columns 2, and electric slide rails 3 are installed on the top of the two support columns 2. In this embodiment, the support columns 2 slide to drive the electric slide rails 3 to move. This embodiment is suitable for use in engraving machine bodies 1 with smaller volume.

[0030] Working principle: The electrical components mentioned in this application are all connected to an external power supply and control switch during use. After the utility model is installed, first check the installation, fixation, and safety protection of the utility model, and then it can be used. During use, place the engraving drill bit or laser pointer between the two clamping blocks 9, connect the motor 14, and make the motor 14 drive the double threaded rod 7 to rotate. The double threaded rod 7 drives the other double threaded rods 7 to rotate through the coupling 11 and the connecting shaft 12. At the same time, the double threaded rod 7 drives the pulley 152 to rotate, and the pulley 152 drives the pulley 151 to rotate through the connecting belt 153. The pulley 151 drives the double threaded rod 71 to rotate, so that the double threaded rod 7 and the double threaded rod 71 drive the two sliders 8 to move relative to each other. The sliders 8 drive the clamping blocks 9 to move and clamp the engraving drill bit or laser pointer. A single motor 14 drives multiple clamping blocks 9 to move synchronously.

[0031] During the clamping process of the clamping block 9 holding the engraving drill bit or laser pointer, since the double threaded rod 7 and the double threaded rod 71 are driven to rotate by the motor 14, the clamping block 9 continues to move even after it has firmly clamped the engraving drill bit or laser pointer. In order to reduce the wear on the surface of the clamping block 9 and the engraving drill bit or laser pointer, this application installs a rubber plate 20 on the concave surface of the clamping block 9. When the engraving drill bit or laser pointer comes into contact with the rubber plate 20, the rubber plate 20 will compress the spring 17 through the connecting block 19 and the inner sliding plate 18. The spring 17 is compressed and deformed, reducing the wear on the surface of the clamping block 9 and the engraving drill bit or laser pointer. The protrusion 23 installed on the convex surface of the rubber plate 20 reduces the friction between the rubber plate 20 and the clamping block 9, which is highly practical.

[0032] After the user has secured the engraving drill bit or laser pointer, they place the engraving workpiece on the top of the processing table 10, causing the support column 2 to slide on the side wall of the engraving machine body 1. The clamping plate 5 moves up, down, left, and right through the electric slide rail 3 and the connecting box 4, allowing the engraving drill bit or laser pointer to perform engraving operations on the workpiece.

[0033] Example 2: Please refer to Figure 6 A carving machine clamping device, which differs from Embodiment 1, has two support columns 2 symmetrically fixedly installed on the top of the carving machine body 1. Electric slide rails 3 are installed on the top of the two support columns 2. The processing table 10 is slidably connected to the top of the carving machine body 1. By sliding the processing table 10 on the top of the carving machine body 1, the carving workpiece is moved to the bottom of the carving drill bit or laser pointer, thereby performing carving. This embodiment is suitable for use with a larger carving machine body 1.

[0034] The engraving machine body, electric slide rail, connecting box, processing table, and coupling in this case are existing technologies. The engraving machine body, electric slide rail, connecting box, and processing table all have the same structure and connection method as those in the cited documents. As long as the engraving machine body, electric slide rail, connecting box, processing table, and coupling meet the requirements of this case, they are all acceptable.
